Auto-flagged for DWI annual return · significant event review

Private Water Supply oversight is a niche, statute-bound discipline — and Officer Assist treats it that way. PWS risk assessments, sampling schedules and DWI returns share one engine.

Legionella incident investigations and pool/spa inspections sit alongside, so a cluster of cases at a single premises is hard to miss.

How it works

The water safety workflow, end to end.

  1. 01

    Assess the supply

    PWS risk assessments run through Regulation 6 and 7 logic with sampling schedules generated from the result.

  2. 02

    Schedule and sample

    Annual sampling rounds, lab dispatch, and result reconciliation all live in the supply record.

  3. 03

    Report to DWI

    DWI annual returns and significant event notifications generate from the live data — no separate spreadsheet.
